PRESIDENT’S MESSAGE
Greetings SPE Members.
November is here, and I can’t help but think about all the things that I am thankful for. One of those items is being a part of this society that has not only broadened my involvement within the plastics industry, but has given me ties and experiences that will always be of such great benefit to me.
If you are reading this message, then you are in some way connected to the Southern California Section of SPE. You might have attended a dinner meeting, or a plant tour, maybe received an SPE scholarship, exhibited at our tradeshow, maybe you came out to play a game of golf with us, or, you are one of the devoted volunteers that makes this engine turn. Whichever it may be, I would like to extend a huge thank you for supporting this society’s efforts and helping us to uphold to the SPE mission, which is “to promote scientific and engineering knowledge relating to plastics worldwide and to educate industry, academia, and the public about these advances.”
Enjoy the holiday season and I hope to see you at the next SPE Plant Tour Event, which will take place at Prestige Mold on Thursday November 16th.
All the best,Ashley Spittle SoCal SPE President

SoCal SPE held the first dinner meeting for the new SPE Fiscal Year. We also held the dinner meeting for the first time at Dave & Busters in the City of Orange. Our Presenter was Brian Newsome of Applied Minerals.
Applied Minerals is a manufacturer of Hollow Nano Tube known as Halloysite Clay. This clay is kaolin in nature and is rolled up by mother nature into hollow tubes similar to a rolled-up newspaper. Applied Minerals brand name for the Halloysite Clay is Dragonite. Brian discussed several properties the Dragonite adds to Thermoplastics and even Thermosets.
1) Halloysite is a synergist for non-halogen flame retardants. 2) Halloysite also works as an ATO replacement synergist, for Halogen systems.3) Halloysite provides reinforcement properties.4) Halloysite can be used to provide controlled release delivery additive.5) Halloysite can absorb liquids enabling the masterbatcher the ability to add liquids in a dry form. 6) Halloycite is also used for nucleation/cycle time reduction in a number of polymers.
Brian Newsome’s presentation is available at www.SoCal SPE.org website. We had a positive response to our guest speaker and to our dinner meeting location. Thank you to all the members in attendance.

SMED-Single Minute Exchange Die Part 2: ImplementationVictor Okhuysen, Ph.D., Professor of Manufacturing Engineering, Cal Poly Pomona University
This is the second part of a two part series. This first article covered the benefits of SMED and the key principle. This article will cover step by step implementation of SMED.
As a recap from the past article, SMED is a technique used within lean manufacturing to reduce waste and change over time of tooling. The general benefits include lower costs, better use of labor, increased machine uptime, lower inventories, etc. There are elements of SMED that are virtually free such as organizing tasks between internal and external while there are other aspects to implementation that could require a significant investment. In all cases, a cost/benefits evaluation should be done.
How is SMED implemented? There are many variations to SMED implementation, but they all include the following main steps:
1. Observe and study the current process:
The objective of this observation is to find out everything that happens when executing a changeover and how long it takes. That is, all the steps involved and how long they take. In addition to that, what personnel is necessary for each step.
2. Define necessary steps and identify unnecessary steps and take action to remove them:
When defining the necessary steps different tools will require different steps. I prefer to develop a standard checklist with several Not Applicable slots than multiple custom sheets. Depending on your work mix a few standard checklists may be a better solution, but certainly not one for each mold. Identification of unnecessary steps and their elimination is crucial to a successful SMED implementation. An all too common example of this is having personnel looking for misplaced tools and supplies. One solution to this is to organize a tool and supply crib so that it becomes one stop shopping. For molds that are changed frequently (once/week) it may justify the investment of a supply tray dedicated to this tool. In this manner, all correct length hoses, connectors, special tools can be in one location and all the setup tech needs to do is grab the tray. For molds that have lower usage (once/year) this would not be justified.
3. Classify all (necessary) steps between external and internal:
External steps are those that can be done off line such as retrieving the new mold and collecting all necessary tools and supplies for the changeover. Internal are those where it is necessary to stop the machine. Examples include loading and unloading the mold. Whenever possible, change internal to external steps, such as hooking water lines to the mold. Hooking the lines to the mold can be done as an external step prior to loading to the machine while hooking the lines to the machine has to be done as an internal step.
In addition find steps that can be performed simultaneously (for instance, one person can work on changing the mold, another to change the polymer and machine settings and another one to work on peripherals). One note of caution, use proper lockout/tagout and other safety procedures while having multiple people working on the same cell.

4. Optimize each step with an emphasis on optimizing internal steps:
In this case, look at what the objective of the step is, not just what the action of the step is. For instance, one step could be defined as “threading water hoses to mold.” This can be optimized by providing a tool for threading faster. On the other hand if the task is defined as “connecting water hoses to mold” this opens up the use of quick disconnects and dedicated manifolds. Also note that if the water lines are connected to the mold offline, it does not stop the machine, so this can be done slowly but it makes sense to invest in optimizing the connection of lines to the machine as this is an internal step and the machine must be stopped.
Sample sequence on changing a mold in an injection molding press:
This is a simplified set of tasks using only a few steps for illustrative purposes. More than likely some elements of this are already in place in your changeover operations. The ‘original’ process is defined as 100% sequential, which is not necessarily the norm, but has been observed by the author in some places. The values are estimates, not real time studies. Also note that a similar approach can be done on the plastic side of the machine and any auxiliaries such as robotic unloading, automated packaging, etc.
